The Headlphones Nebula
The image above is a planetary nebula designated Jones-Emberson 1. The planetary was discovered in 1939 by Rebecca Jones and Richard Emberson. It also is designated PK 164+31.1. This designation is from a catalog of objects assembled in 1967 by astronomers Peek and Kohoutek. The first number (164) in the designation represents the galactic longitude and the second (31) the latitude. The number after the decimal point indicates that it is the first to be cataloged within 1 square degree of space[1,2]. It lies in the constellation Lynx at an approximate distance of 1,600 light years from the Earth.
Due to its appearance in telescopic images, this planetary is commonly referred to as the Headphones Nebula. The nebula is relatively dim and the central star is a magnitude 16.8, very hot, blue, white dwarf.
Narrowband filters, Ha and OIII, were used to capture the data for the image. This narrowband data enabled the image to be processed in a manner that emphasized and displayed the faint structure and detail of the nebula. The stars in the image were overlaid with color data obtained from a separate red, green, and blue filtered imageReferences
